Cheetah Suspension or Tiger Cat II Seat?

So I've narrowed it down to the Tiger Cat II or the Cheetah. I'm leaning heavily toward the TCII but there's one question that's still nagging me. How about that suspension on the Cheetah? I'll be mowing a minimum of 5 acres weekly, and the areas that aren't rough are REALLY rough. I've heard the Cheetah suspension is great for fast mowing on washboard lawns. My lawn is closer to a lunar surface in many places so I'll be going a little more slowly and I've gathered that the seat on the TCII might actually be better for that application.

There's no way I'm considering anything but the TCII or the Cheetah. I've wittled my selection down for too long to back up. Anybody care to weigh in on those seats? Thanks
